1. Introduction to Session

Session is a data structure that stores user information and is stored on the Web server in a Web application. When a user browses the website, the server generates a Session and sends its ID to the client browser. When the browser returns the request, it will bring the ID of the Session. The server can find the user's Session through the ID and read or modify the user's information from the Session. The functions of Session can be summarized into the following aspects:

1. Storage user information. For example, the user's login status, shopping cart contents, form data, etc.

2. Realize cross-page data sharing. Such as sharing user information between multiple pages.

3. Ensure that each user has independent data storage space.

In ThinkPHP6, Session is implemented using PHP’s Session mechanism by default, and developers can conveniently operate Session in the application.

2. Session configuration

Session configuration in ThinkPHP6 mainly involves the following parameters:

1. session_name: Session name. Default is PHPSESSID.

2. expire: Session expiration time. The default is 1440 seconds.

3. use_trans_sid: Whether to enable SID transmission. Default is off.

4. auto_start: Whether to automatically start the Session. Default is off.

5. path: Session saving path. Defaults to the system temporary directory.

6. domain: Session domain name. Default is empty.

7. secure: Whether to enable secure transmission. Default is off.

8. httponly: Whether to enable HttpOnly. Default is off.

If you need to modify the Session configuration, you can configure it through the session.php file in the config directory in ThinkPHP6. The specific operations are as follows:

1. Enter the config directory and find the session.php file.

2. Modify the relevant configuration parameters in the session.php file. For example:

return [
    // session name
    'name'           => 'think_session',
    // session auto start
    'auto_start'     => true,
    // session type
    'type'           => '',
    // expire time
    'expire'         => 86400,
    // use database
    'use_database'   => false,
    // data compression
    'data_compress'  => false,
    // cache prefix
    'prefix'         => '',
    // cache expire time
    'cache_expire'   => null,
    // session id
    'id'             => '',
    // session path
    'path'           => '',
    // session domain
    'domain'         => '',
    // session secure
    'secure'         => false,
    // session httponly
    'httponly'       => false,
    // session redis connection
    'redis_connection' => 'session_redis',
    // redis handler
    'redis_handler'  => '',
    // redis session key prefix
    'redis_prefix'   => '',
];

3. Save the file and close it.

3. Use of Session

In ThinkPHP6, the use of Session is very simple. Developers can read and write in the following ways Enter data in Session:

1. Read Session data:

$request = Request::instance();
$session = $request->session();
$value   = $session->get('key');

2. Write Session data:

$request = Request::instance();
$session = $request->session();
$session->set('key', 'value');

In actual development, developers can customize the relevant configuration of Session according to business needs to achieve more flexible and efficient data storage and management.
